it seems hard to make it pure recursive, because I want to use self.tcx.parent_hir_node(..), and local function can not capture self.

Could we rename this to suggest_turning_stmt_into_expr or something?

Rollup merge of rust-lang#121153 - chenyukang:yukang-fix-105431-type-mismatch, r=estebank Suggest removing superfluous semicolon when statements used as expression Fixes rust-lang#105431 - it's not a pure recursive visitor, so I guess there may be some more complex scenarios not covered. - moved `consider_removing_semicolon` to `compiler/rustc_infer` for reusing this helper function.
